A blog sharing information about materials presented to children on climate, highlighting those intended to frighten or mislead, and those which seek to inform and inspire rather than to recruit, even the very young, for an ill-founded political campaign around the threat of CAGW. A campaign which is irresponsible, destructive, divisive, and degrading.

'First, the non-climatic effects of carbon dioxide are dominant over the climatic effects and are overwhelmingly beneficial. Second, the climatic effects observed in the real world are much less damaging than the effects predicted by the climate models, and have also been frequently beneficial.'

The Augean Stables of Climate Materials for Schools - an example from the teaching of English language in Germany

So many people have been duped by climate dogma which
insists on catastrophic effects from rising CO2 that signs of it appear in all
sorts of places. It can of course be
found in geography and popular science books for children, and in many websites, but it can also be found in language
lessons. I myself came across it while
studying French. Here is
an example from a textbook used for teaching English in high schools in Germany,
well-annotated by critical observers from the policy think-tank KE Research:

# “Greenhouse gases” and clouds continuously radiate energy into
outer space. Thereby they cool the atmosphere. This enables the atmosphere to
cool the ground. This has been going on over billions of years.

# Since IR active
gases cool the Earth (at least indirectly), an increase in their concentration
cannot cause a raise of temperatures. This constitutes a disproof of the CO2
warming hypothesis (yellow block in the “GreenTower”
in fig. 1).

# All further claims of the climate dogma (computerized
climate prophecy, apocalyptic consequences, need of political action and
“climate protection”) would only make sense if the CO2 warming hypothesis is
proven. But as the hypothesis is demonstrated invalid by our comparison with
the Moon, the claims derived from it as well as the actions suggested make no
sense. The entire CO2-based “climate research” proves to be pseudo science – or charlatanism.

# In certain countries, public education is misused by
governments to implant fears in the brains of students – being the result of a
wrongly built understanding of nature.

This is right at the heart of the debate, or rather it ought
to be. Instead these are amongst the
so-called ‘sceptical’ views that are often ridiculed or ignored. But the basic assertion that radiation in
infra-red from the atmosphere to space is an important component of Earth’s
cooling mechanism is correct. Their second point is far more contentious. It is not clear to me what the overall, or net effect of CO2 in the climate system is. I can also go along with a modest warming contribution of CO2 thanks
to it delaying heat loss from the surface to space by absorbing Earth radiation (in the relevant narrow bands for CO2) before re-emitting it in all directions.
Simple calculations suggest a value of the order of 1C for this warming
for every doubling of ambient CO2 levels. One day, perhaps we shall see computer modelling of CO2 in the climate
system. We do not have that at present. Instead the GCMs have proven to be a rather
expensive way of confirming that when you suppress heat loss from an exernally
heated object, that object’s temperature will, all else being equal, rise. This is done in the models by imposing an
instantaneous drop in radiative heat loss at the outer edge of the atmosphere for a given
increase in ambient CO2. This paper by
KE Research is one which suggests that the role of CO2 is more complicated than
that. The current GCMs cannot help
resolve this since they work from a presumed net effect of CO2, i.e. they
incorporate a conclusion rather than discover it from the model runs.

My thoughts have tried to address the question "Well, what would Hercules do?" I didn't get very far. As he hasn't been around for a while, I couldn't just ask him. The best I could come up with, was to push for a heavy dose of libricide - then I realised, it isn't the books that I really want to burn.....

Observed and Expected Temperatures

Scafetta Model
This displays a forecast made by Scafetta using a simple model combining various cycles which have been observed in temperatures, together with some 'adjustment for global warming'. His forecast has the light blue background. An IPCC 2007 'projection' is shown with a green background. The bold red-then-blue line is the HadCRUT calculation of a global mean temperature, with blue line connecting the most recent results. (Source: Tallbloke's blog).
